Button-sliding-type opening/closing device for a cosmetic container

Abstract

The present invention relates to a button-sliding-type opening/closing device for a cosmetic container consisting of a vessel for storing cosmetics in a liquid or gel state, and a discharge pump coupled to a top inner portion of the vessel for discharging cosmetics by applying external pressure thereto, wherein the button-sliding-type opening/closing device comprises: a shoulder ( 20 ) coupled to the top portion of the vessel ( 10 ); a button body ( 30 ) inserted into the shoulder ( 20 ) and upwardly and downwardly movable; and a button ( 40 ) slidably coupled to a top surface of the button body ( 30 ), for opening and closing a cosmetic pumping hole ( 31 ) in the button body ( 30 ), as well as for preventing the button body ( 30 ) from being pressed and actuated.

What is claimed is: 
     
       1. An open and close apparatus of a button sling type for a contents instrument, the apparatus comprising:
 a container receiving contents in a liquid state or gel phase; 
 a discharging pump connected to an inner upper part of the container for discharging the contents; 
 a shoulder connected to an exterior upper part of the container; 
 a button body inserted into the shoulder and movable vertically; 
 a button which is slidably connected to an upper surface of the button body, and is movable in the backward and forward directions with respect to the button body and thereby closes and opens a contents pumping hole of the button body and, wherein the botton is incapable of moving vertically downward when in a retracted, closed position; and 
 a guide cap for guiding a sliding of the button on an upper surface and front part of the button body and configured to uncover a front lower surface discharging hole of the button when the button is moved forward and upward. 
 
     
     
       2. An open and close apparatus of a button sling type for a contents instrument, the apparatus comprising:
 a container receiving contents in a liquid state or gel phase; 
 a discharging pump connected to an inner upper part of the container for discharging the contents; 
 a shoulder connected to an exterior upper part of the container; 
 a button body inserted into the shoulder and movable vertically; and 
 a button which is slidably connected to an upper surface of the button body, and is movable in the backward and forward directions with respect to the button body and thereby closes and opens a contents pumping hole of the button body and, wherein the button is incapable of moving vertically downward when in a retracted, closed postion, 
 wherein the button body has an opened lower surface and a concave-curved upper surface, and the button body further comprises: 
 a pair of sliding holes formed symmetrically on the upper surface of the button body and which is configured to receive a plurality of leg units of the button such that the plurality of leg units of the button slide thereon; 
 a side wall which is disposed on each side of each of the pair of sliding holes and is configured to be connected with a stumbling protrusion located on a lower portion of the leg units; and 
 a guide cap for guiding a sliding of the button on an upper surface and front part of the button body and configured to uncover a front lower surface discharging hole of the button when the button is moved forward and upward, and 
 wherein the contents pumping hole which is formed in a center of the upper surface of the button body and corresponds to a discharging hole of the discharging pump. 
 
     
     
       3. The apparatus of  claim 2 , further comprising:
 a sliding limitation hole on a peripheral region of the contents pumping hole of the button body, wherein a lower hole protruding to a lower part of the button is inserted in the sliding limitation hole such that the button is not excessively slid. 
 
     
     
       4. The apparatus of of  claim 2 ,
 wherein an upper surface of the button has a concaved curved surface shape corresponding to the upper surface of the button body, 
 wherein the plurality of leg units are formed on a lower surface of the button and inserted respectively into the pair of sliding holes of the button body, and 
 wherein each of the plurality of leg units comprises:
 a guide protrusion which is guided along one of the pair of the sliding holes; 
 a leg protruding respectively downward at a rear end of the guide protrusion; 
 the stumbling protrusion engaging the side wall of the button body and located on the lower portion of each of the leg units; 
 a lower hole facing downward and positioned behind a center line of the pumping hole in a locked position; and 
 a front lower surface discharging hole which is communicated with the lower hole and discharge the contents to a front side lower surface of the button. 
 
 
     
     
       5. The apparatus of  claim 2 ,
 wherein the shoulder comprises: 
 a screw connection portion to be screw-connected to an upper outer peripheral surface of the container at a lower part thereof; 
 a cylindrical protrusion protruding upward the screw connection portion, having smaller inner diameter than that of the screw connection portion; 
 an inner protrusion protruding in a circular form and leaving a groove spaced at a predetermined distance from the inner peripheral surface of the cylindrical protrusion, the groove being defined by the cylindrical protrusion and the inner protrusion and being configured to receive the button body; and 
 a stepped surface formed at a low level and leaving a hollow space on a center of the inner peripheral surface of the inner protrusion.
